A posture subspace in primary motor cortex

The paper shows that posture and goal information in motor cortex are organized in separate, orthogonal subspaces, with posture information being stable across tasks.

Dynamical constraints on neural population activity

This study challenges monkeys to reverse natural neural activity time courses in motor cortex using a BCI, finding they cannot violate these time courses, supporting the idea that neural activity reflects network-level computations.

The dorsolateral striatum encodes a temporal basis for the organization of behavior

The paper shows that DLS neural activity in rats correlates with temporal behavior, particularly in response to the second of two sequential stimuli.

Dopamine responses reveal efficient coding of cognitive variables

The paper investigates how reward expectations are influenced by internal representations in rodents, finding that efficient, compressed representations best match both behavior and dopaminergic activity.

Striatal dynamics explain duration judgments

This study shows that striatal neuron dynamics predict and are necessary for duration judgments in rats performing a psychophysical task.
